The Crow and the Raven

A Crow became very jealous of a Raven, because the latter was
regarded by men as a bird of omen which foretold the future, and
was accordingly held in great respect by them. She was very anxious
to get the same sort of reputation herself; and, one day, seeing
some travellers approaching, she flew on to a branch of a tree at
the roadside and cawed as loud as she could. The travellers were in
some dismay at the sound, for they feared it might be a bad omen;
till one of them, spying the Crow, said to his companions, "It's
all right, my friends, we can go on without fear, for it's only a
crow and that means nothing."

only make themselves ridiculous.
